Rheological modelling of high‐temperature stationary creep tests of Grade S275JR steel

Abstract

The paper presents a new validation study of a unified rheological model, in reproducing creep strains from a recent experimental study performed on grade S275JR coupons. The objective of this research is to further test the modelling capabilities of the proposed rheological model and its validity for application in general structural fire engineering analysis. The rheological model is composed of two serially connected Kelvin-Voight elements, used to represent the material's sensitivity to strain-rate-governed changes of yield strength, temperature and heating rate. The paper presents the performance of the model in stationary-creep conditions.
